As the picture helps to illustrate, a healthy soil food web consists of many different animals, arthropods and microorganisms feeding on each other. Having a healthy aerobic soil food web means that harmful species are kept in check. When this goes out of balance, we may need to intervene. We can do this by promoting a healthy SFW. We can also try some other techniques such as using a microorganism to out compete its foes or using a pesticide such as Neem to target unwanted species. It is my opinion that a healthy soil food web is the best option, but that may not always be practical in your unique situation
- A combination of Neem oil and potassium silicate every week is a great option for prevention of various pests, mites, gnats, thrips, or every 3 days for infestation.
- Beauveria Bassiana weekly for prevention of mites, thrips and other arthropods or every 3 days for infestation can be very effective
- Nematodes from www.bioforce.co.nz are fantastic for gnats
- Mite-e from Bioforce NZ is a good mite control agent.
- A bio complete compost can have the nematodes already in to prevent gnats or slugs and many other issues. A healthy diverse soil food web can go a very long way to very little pest pressure.
- Monitoring your vapour pressure deficit in greenhouses can go a very long way to preventing mold and mildew, the results of high humidity. While mites are the result of dry conditions. Monitor and control your VPD https://pulsegrow.com/blogs/learn/vpd
- Applying Trichoderma spores, to out compete all other fungi, the drawback here is you will out compete beneficial fungi also.
- Applying Bacillus Subtilis to activate resistance in plants and inhibit pathogens
